No problem bro, I hope everything turns out okay for ya. Here's one more tip, that might help....
...if you want to feed them, but are worried about overfeeding, start foliar feeding them. It works great, and if your plants are lacking something, they'll absorb only what they are lacking, and nothing else, filling any unseen deficiencies, or deficiencies that haven't shown yet. Then, even if your soil is lacking something, it won't be a problem. It's a good safety-net to use, especially if you are uncertain of feeding times.
I use my Dynagro Grow, mixed at 1/2 strength, PH'ed to about 6.5, for foliar feeding. Do that once a week, or so, and it'll be smooth sailing(for veg, anyway. Flowering can be a different story.lol). Just remember to alternate a fresh water bath,(spray them with water only) between every 1-2 foliar feeds, to keep everything rinsed and clean.
